Cell Cycle Phases (G1, S, G2, M) · NCERT Biology

In animal cells, besides DNA replication in the nucleus, which of the following events occurs in the cytoplasm during the S phase?

  1. Spindle fiber polymerization
  2. Centriole duplication in cytoplasm
  3. Nuclear envelope breakdown
  4. Protein synthesis for G1 preparation
Show answer and explanation

Correct answer: Centriole duplication in cytoplasm

During the S phase, DNA replication begins in the nucleus, and the centriole duplicates in the cytoplasm. This is essential for the later formation of the mitotic apparatus.
